Modified iconic lizard by M. C. Escher in 3 dimensions. The top is drafted at 60° to create artistic striations of the profile when printed with a standard .010 inch per layer FDM printer. The individual pieces interconnect on a 1 inch hexagonal pattern. I find this to be a good example of the accuracy and ressolution of these printers. The parts are line to line and snap together nicely. X and Y coordinates show the limit of resolution and the Z coordinate shows the comparative coarseness of detail in that axis.

I pasted and scaled a jpg and traced the Escher Lizard in SolidWorks over a 1" Hex. Then I deleted the lines that were rotations of the profile. I then rotated the profile 120° on the appropriate verticies of the hex. I extruded once straight and again with draft. The image needed a bit of adjusting to create common planes and a bit of symetry for the head.
